Abstract

The invention provides a touch display panel and a touch display device. The touch display panel comprises a first substrate, a plurality of first touch electrode sets and at least one first virtual electrode. The first touch electrode sets are located on the first substrate and arranged in the first direction, and each first touch electrode set comprises a plurality of first touch electrodes which extend in the second direction and are arranged in the first direction. The first virtual electrodes are located on the first substrate and located between the corresponding adjacent first touch electrode sets, and the first virtual electrodes are connected with fixed potential or suspended. According to the touch display panel and the touch display device, the touch performance of the touch display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] With the development of human-computer interaction technology, touch technology is increasingly used on various displays. Capacitive touch technology is widely used due to its advantages of wear resistance, long life, low maintenance cost for users, and support for gesture recognition and multi-touch. [0003] Capacitive touch technology can be divided into self-capacitive touch technology and mutual-capacitive touch technology according to the detection method of capacitance between different objects. Self-capacitive touch technology detects the presence, position, and motion of an input object on a touch screen based on changes in capacitance between the input object and electrodes. The mutual capacitive touch technology detects the existence, position and movement of an input object on t...
